mental-in- Lamps for BurningHydrocarbon-Oils; and

cbrrectdcscripticm thereof, reference being had to the accompanyingdrawings, and to the letters of reference thereon. v

My invention relates to lamps wherein a gas-jetflame is produced inlamps that burn wicks, by means of a jet of air fi'om a jet-pipe ornozzle similar to'a bat-wing or fish-tail gas-burner, the jet of airunderpressure being forced to mingle with the products of combustionfrom V a surrounding wick, as in Letters Patent oftheUnited States,granted to, me,.bea'1 i.ng date the 26th of No- 'In that patent, a formof construction is described and shown, adapted to'burn lighthydrocarbomoils, and

which will also burn the-heavier oils, commonly called kerosene-oils. vI t ButI have-discovered-that, in burning the heavier oils in saidlamps, the-wick becomes encrusted with solid matter arisingfrom the.combustion, and that such accumulations cause the lamp to smoke, unlesstrimmed oftener than is convenient in the use of lamps,

said invention, which consists in'combi'n'ing with the .aiajet pipe, twowick-tubes, which may be flat at their lowerends,'zu 1d also at thepoint of unionwith the lamp-cap,but which are curved, at theburning-point, in the form of segments of a circle, thetwo segmentsbeing placed oppositeeach other, with thejet-pipe be tween them, in themanner shown in the drawings, and so as to allow air to come in contactwith the wicks at their side edges, the segmentsbeing separateda little-.l'rombach other for that purpose. 3
